IMPROVEMENT lN FIRE-PROOF MANSARD ROOFS.

Specification forming part ofLetters Patent No. 149,480, dated April 7,1874; application filed March 9, 1874.

To all whom it may concern:

Be it known that I, MINARD H. FOWLER, of New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Mansard Roofs; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form a partof this specification.

The nature of my invention relates to an improvement in Mansard roofs 5and it consists in open-faced tiles, each one of which has a number offlanges formed upon the top of the base-plate, in between which flangesmortar or cement is poured, for the double purpose of securing the tilestogether and forming a means of fastening the tiles in position, as willbe more fully described hereafter.

The accompanying drawings represent my invention.

a represents the supporting iron rafters, which extend parallel up theside of the roof, and upon which the tiles are supported. These raftersmay be made of cast-iron, having alternate flanges upon each side, so asto stiffen the rafters and to support the tiles in position, or

they may be of any other form desired. The tiles consist of thebed-plate 0, upon the face of which are formed a number of flanges, c,of any suitable height or thickness. Generally I prefer to form four ofthem, one upon each edge, which abuts against the flange on theadjoining tile, and two in the center of the plate, which are just nearenough together to receive a good layer of mortar or cement, (7, intowhich the nails which hold the slate in position are driven.

By thus forming the tiles with open faces and flanges, much shorter andsmaller pieces of slate can be used; or the slate can be put on inlayers of three or more thicknesses, if so desired, where the pieces areslightly longer than usual. The tiles are' much lighter, and can be muchmore cheaply made.

Having thus described my invention, I claim- Tiles for roofs, consistingof the bed-plate c and flanges e, substantially as set forth.

In testimony that I claim" the foregoing, I have hereunto set my handthis 3d day of March, 1874.
